BUNDLE-TRANSFER FOR GRAIN-BINDERS.

To all whom z'may concern.'

Be it known `that I, Louis ANDERSON, a citizen of the United States, and resident of Chicago, county of Cook, and State of Illinols, have invented certain new anduseful Improvements: inV Bundle-.Transfers for Grain-Binders, of which the following. is a Yuse upon harvesting machines, such for exj ampleas that shown in my application for patent on shock formers for gra-in binders,

led October 1 1908, Serial No. 455,654, wherein a backwardly tilting cradle is provided for collectinga number of bundles of grain and then depositing them upon the ground in the form of a shock. It is well known that grain binders receive the freshly cut grain with the .butt ends of the stalks turned in the direction of travel of the machine; whereas, if the bundles are to be deposited uponl the ground in the form of a shock by means of a backwardly tilting cradle, they must be turned end for end in order that the grain may stand unpright in the shock.

The invention contemplates improved means for transferring the bundles of grain from the table of a harvesting machine, upon which the bundles are tied, to a shockforming or other cradle adapted to deposit the bundles upon the ground, the bundles being turned end for end in transit.

The object of the invention is to simplify and improve the construction of bundle transfer of the kind described, whereby they are rendered more certain in their operation.

In the accompanying drawings, Figure 1 is a plan view of a bundle transfer embodying the features of improvements provided by the invention, details of a harvesting machine being also shown; Fig. 2 is a side elevation of the same, some of the parts being shown in section; Fig. 3 is a sectional view 'taken on the line 3-3 of Fig. 2; Fig. 4 is a detailvsectional view taken on the line ofFig. 1; Fig. 5 is a detail perspective view; Fig. 6 is a sectional view taken on the line 66 of Fig. 1; and Fig. 7 is a sectional viewV taken on the line 7-7 of Fig. 6.

Specification of Letters Patent.

Application filed. March 27, 1911.

Patented Sept. 9, 1913. Serial No. 617,303.

Details of a frame of a harvesting ma` chine are shown in the drawings at 10. The platform upon which the bundles of grain are tied is shown at 11, and details of a shock-forming cradle appear in Fig. 1 of the drawings at l2.

The apparatus provided by the invention is intended to transfer the bundles of grain as X, one at a time, from the platform 11 to the cradle 12 and turn them end for end in transit. As shown, a forwardly inclined tubular post 13 rises from the platform 11 adjacent its rear end. The base 14 of the post 13 is rigidly secured to the platform 11, as by lag screws 15, and serves to support the post in xed position.v A tubular shaft 16 extends vertically through the post 13 and carries a forked bracket or head, generally designated 17, at its Vhigher end. The head 17 is seated upon the top of the post 13 and is rotated thereon by the turning of the tubular shaft 16 to which it is fixed in an angularly adjusted position as by set screws 18. A pair of bundle-grasping arms 19, 20, project laterally from the head 17. As shown, the head 17 is provided with two pairs of arms as 21, 22, and 23, 24. Each pair of these arms provides a double support for one of the bundle-grasping arms 19, 20, the ar1n19 being rotatably mounted in the arms 21, 22, and the bundle-grasping arm 20 being preferably fixed aga-inst rotation in the arms 23, 24. One of the bundlegrasping arms, as the non-rotatable arm 20, carries at its outer end a depending -fork 25. rIhe fork 25 is preferably rotatably mounted at the end of the arm 20, as by being secured to the lower end of the vertical shaft 26 which turns in a vertically disposed bearing 27 formed upon the end of the arm 20. A crank 28 is applied to the higher end of the vertical shaft 26 for turning the fork 25. The bundle-grasping arm 19 has a laterally projecting prong 29 formed upon its outer end and this prong cooperates with the fork 25 to grasp a bundle of grain as X upon the turning of the arm 19. For increasing the rigidity of the parts the arms 19, 20, are preferably connected adjacent their outer ends as bya tieplate 30, with which the arm 19 has rotative engagement, and the arm 19 is offset beyond the tie-plate as indicated at 31, whereby the prong 29 is lowered by the turning of the arm.

In the operation of the device the bundlegrasping arms'19, 20,r are swung betweenY positions in which theirouter ends are located over the platform 11 and over the cradle 12, respectively, by the turning of the tubular shaft 16. Preferably during the y formation of the bundle as X upon the platform 11 the arms 19, 20, occupy the 'intermediate position illustrated by full lines in Fig. 1 of the drawings. When a bundle as X has been completed upon the platform 11 the arms 19, 20, are rst swung upwardly,

as viewed in Fig. 1, to a position over the; platform 1l; the arm 19 is then rotated to grasp the bundle between the prong 29 and fork 25. The tubular shaft 16 is then rotated to swing the .arms 19, 20, outwardly,

i Vas viewed in Fig. 1, until the bundle X reaches a position over the cradle 12, when thearm 19 is Vgiven a partial counter rotation to raise the prong 29 and release the link 32, to a xed support, such as the standard 33 located in front of t-he post 13. As

shown, the standard 33 rises from the platforniA 11 and the link 32 is connected to the top of the standard 33 by a swivel 34. Thel standard 33 is most conveniently provided with an integral base 35 through which screw bolts 36 are passed for permanently securing the standard to platform 11, and the standard is of such height that the link 32 is located below the plane through which the 1 to longitudinally.reciprocate the pitman 60 y ar-ms 19, 20, swing.

Power for turning the tubular shaft 16` and rotating the arm 19 is most loonveniently .derived from a continuously rotating shaft 37 of the harvesting machine. vAs

shown, a sleeve 38, is loosely mounted on the Y vertically arranged rock shaft 47 and a crank arm 48 is secured to the higher end-of l shaft 37, and a two-faced cam 39 is fixed; upon the Vsleeve 38, as by a key 40, to be rotated by the turning of .the sleeve.

For intermittently connecting the sleeve 1 38 with the rotating shaft 37 to cause said sleeve 38 and cam 39 to be turned through a single complete revolution, clutch mechanism, most clearly shown in Figs. 2 and f6 of the drawings, is employed. A ratchet 41 is iXed upon the shaft 37 adjacent the end -of the sleeve 38, as by akey 42, and aclutch Larm 43 is pivotally mounted between a pair of laterally projecting lugs 44, 45, formed upon the sleeve 38 adjacent its end to lextend over the ratchet 41. A cam finger 46 norl mally supports the clutch arm 43 clear of the ratchet 41, but is withdrawn from engagement with the clutch arm 43 when the bundle i transfer mechanism is to be operated. As,

shown, the cam nger 46 is carried by a the rock shaft 47 for turning the rock shaft and withdrawing the cam linger.V 46 fromv engagement with the. clutch arm 43, The' end 49 of the cam linger 46 is inclined and when the sleeve 38 has been turned through a complete revolution by the engagement of the ratchet 41 with the-clutch arm 43, .the

end of the clutch arm 43 rides upon the cam finger 46 'and-"israised thereby out of engagement with the ratchet 41 to permit the` sleeve 38 to come -to rest.

Operative mechanism including a?V bell-Y crankv lever 5() pivotally"A mounted upon a bracket 51 secured to the underside of `platform 11, isactuated'by oneV of the faces asv 5 2 of the cam 39to vturn the tubular shaft 16 and swing the bundle-grasping arms 19,V

20. As shown, the lower end of the tubular Y' shaft 16 extends through-an opening V53 in the platform 11 and has applied theretobe-f 4low the platforuna :crank arm 54 which is connected by a link 55 Ato onevofthearms of the bell-crank lever 50. The other arm of the bell-crank lever 50 is connectedfby a link 56 to' one armV of a second bell-crank' lever 57'which 'is'pivotally mounted to swing in a vertical plane upon a bracket 58V secured to an upright member as 59 of thelframe 10 of the harvesting machine. The other arm of the bell-crank lever-57. has secured to it pitman 6 0 which extends downwardly therefrom and has a' bifurcated lower end 61 which straddles the sleeve38 andshaft37 andV is in sliding engagement with the sleeve. A cam roller .62 mounted upon theside of thej pitman 60 adjacent its lower end coperates with the cam facey52 of the cam Vplate39 This crank arm is connectedto the higher.A

end of the rod lG3 bya link 65.V Mechanism including a rock shaft 66, which is journaled in the .bracket 67, mounted upon vthe upright member 59. of the frame 10 of the harvesting machine below the platform 11, is actuated Y by the other face 168 yof. the cam plate 39 to vertically reciprocate the rod 63. lAcrank arm 69 mountedlupon oneV end of the rock shaft `66, Vis bifurcated at its end, as most "clearly :shown at 70 Fig. 3. The two parts'.

of the bifurcated end 0 of this Vcrank arm straddle Ya sleeve;` 71, which is rotatably mounted on the rod 63, but fixed against longitudinal movement thereon betweenV collars 7 2 and '7 3. Oppositely formed lugs ,74, 7 5,"

formed on the sleeve 71, run in longitudinally slotted apertures .as 76 formed in theV two parts ofthe bifurcated end 70 of `the crank arm. A second crank .arm'77 mountedon `the rock shaft 166 is-connected to the" higher end a pitman 78..- Thelower vend,

7 9 of the pitman 78 is bifurcated and straddles the sleeve 38 adjacent the cam plate A cam roller 8O mounted upon a side face of the pitman 78 adjacent its lower end coperates with the cam face 68 of the cam plate 39` to vertically reciprocate the pitman 78 and turn the rock shaft' 66 to vertically reciprocate the rod 63. Preferably the lower end of the rod 63 is stayed by being extended through a bearing block 81 located below the sleeve 71 and collars 72, 73. The lower end of the rod 63 has both rotative and longitudinal sliding engagment with the bearing block 81, and the bearing block 81 is fixed in position in any convenient manner as by being secured to the upright member 59 of the frame 10 of the harvesting machine.

Preferably a counter-poise is provided for supporting a bundle X of grain, which is hung between the outer ends of thc bundlegrasping arms 19, 20. This is conveniently provided by extending the arm 20 beyond the head 17 of the tubular shaft 16 from the fork 25 as indicated at 82, Figs. 1 and 2, and by slidingly mount-ing a weight 83 upon the part 82. Preferably the weight 83 is longitudinally apertured to receive the part 82 and anti-friction rollers 84 are mounted in recesses 85 formed in the weight adjacent the aperture. Provision is preferably made for sliding the weight 83 outwardly upon the part 82 when the arm 19 is rotated to cause the prong 29 to engage the bundle and for sliding the weight 83 inwardly upon the part 82 when the arm 19 is reversely rotated to cause the prong 29 to release the bundle. As shown, a bracket plate 86 is xedly mounted upon the head 17 and extends rearwardly therefrom alongside of the weight 83. A U-shaped lever 87 is pivotally mounted at 88 upon the rear end of the bracket 86 and one arm of the lever 87 is connected by a link 89 t-o t-he weight 83, and the other arm of the lever 87 is slotted, as indicated at 90, to slidingly receive a stud 91 mounted upon the higher end of the rod 63. vByv this means vertical reciprocatio-n ofthe rod 63 which rotates the arm 19 also slides the weight 83 back and forth upon the part 82.
